CHIANTI IDL version 10.2.1 released, December 2023

The IDL CHIANTI distribution has been updated to version 10.2.1. The distribution includes two new routines and updates to 16 routines. Changes include bug-fixes for the continuum calculation when there are a large number of bins, and improvements to the line list print-outs from ch_ss.

Solarsoft users should update their distribution to receive the new updates. Users of the standalone database should visit the Download page to access the new version.

The database remains the same, and the current distribution is 10.1.

We are grateful to individual scientists and funding agencies for their support.
